plus size and pregnant

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​13 weeks today. plus size body. Some people say I'm showing but I'm concerned and embarrassed it's just podge. I am keeping an eye on my weight and so far I haven't gained any yet my waist line is expanding when I take measurements. For a first baby I just feel it's too early to be showing. what do you all think? I'm trying to wear clothes that will hide my "bump" because I think I just look podgy.
